Answer:
the answer is A
Step-by-step explanation:
if you multiple 6 to 4 you get 24. if you multiple 24 to 6 you get 144. if you multiple 144 to 6 you get 864.
Answer:
t = -2
Step-by-step explanation:
5t - 26 = 18t
Add 26 to both sides:
5t - 26 + 26 = 18t + 26
Simplify:
5t = 18t + 26
Subtract 18t from both sides:
5t - 18t = 18t + 26 - 18t
Simplify:
-13t = 26
Divide both sides by -13:
-13t/-13 = 26/-13
Therefore:
t = -2

(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain
For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:
x: number of hours studied.
y: test scores.
The linear relationship would be of the form:
y = mx + b
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
y = 8x + 40
For three hours of study we have that the note would be approximately:
y = 8 * (3) + 40
y = 64
(c) What does the number 40 in Part (b) mean in the context of the situation?
The number 40 means that if you do not devote any study time, then you expect the test score to be 40.
